Abstract

A system for rating information retrieved from a computer network includes a server and a client. The server includes a rate module that generates a rate file for documents retrieved from the network. A client includes a screen module that accesses the rate file to prevent access to certain documents by the user of the client.

Claims

1. A system for rating information retrieved from a computer network, comprising:

a retrieve module coupled to the computer network and operable to retrieve a document from the computer network using a document address;

a rate module coupled to the retrieve module and operable to generate a document rating for the document in response to the content of the document; and

a database operable to store the document rating and the document address.

2. The system of claim 1, further comprising a rating rule database coupled to the rate module, the rating rule database operable to store a plurality of rating rules, each rating rule having an associated rated word and a numeric value indicating the degree to which the rated word is inappropriate, objectionable, or offensive.

3. The system of claim 1, further comprising a rating rule database coupled to the rate module, the rating rule database operable to store a plurality of rule-sets, each rule-set comprising a plurality of rating rules associated with a rating category.

4. The system of claim 1, wherein the document rating corresponds to one of a plurality of age-based categories, each age-based category being defined as a range of the document rating.

5. The system of claim 1, wherein the document address comprises:

a uniform resource locator address; and

an Internet protocol address.

6. The system of claim 1, further comprising a remote computer coupled to the database and operated by a user having a user rating, the remote computer operable to receive the document address specified by the user and to retrieve the document rating identified by the document address, the remote computer further operable to prevent retrieval of the document from the computer network by comparing the document rating and the user rating.

7. The system of claim 1, further comprising a remote computer coupled to the database and operated by a user having a user rating, the remote computer comprising:

a second database coupled to the database, the second database operable to store the document rating and the document address;

a screen module coupled to the second database, the screen module operable to receive the document address specified by the user and to retrieve from the second database the document rating identified by the document address; and

a second retrieve module coupled to the computer network and operable to retrieve the document in response to a comparison of the document rating and the user rating.

8. The system of claim 1, further comprising a remote computer coupled to the database and operated by a user having a user rating, the remote computer comprising:

a second database operable to store an override document rating associated with the document address, the override document rating being different from the document rating stored in the database;

a screen module coupled to the second database, the screen module operable to receive the document address specified by the user and to retrieve from the second database the override document rating identified by the document address; and

a second retrieve module coupled to the computer network and operable to retrieve the document in response to a comparison of the override document rating and the user rating.

9. The system of claim 8, further comprising an update module coupled to the second database, the update module operable to communicate the override document rating and the document address to a remote site.

10. A method performed on a computer for rating information retrieved from a computer network, comprising:

retrieving a document from the computer network using a document address;

retrieving a plurality of rating rules, each rating rule having an associated rated word and a numeric value indicating the degree to which the rated word is inappropriate, objectionable, or offensive;

applying the rating rules to the retrieved document in order to generate a plurality of rule ratings;

summing the rule ratings to generate a document rating; and

storing the document rating and the document address.

11. The method of claim 10, further comprising the step of communicating the document rating and the document address to a plurality of remote computers.

12. The method of claim 10, wherein the document address is specified by a user of the computer.

13. The method of claim 10, wherein the step of retrieving the document comprises:

retrieving a first document; and

retrieving the document using the document address specified in the first document.

14. The method of claim 10, wherein the plurality of rating rules are organized into a plurality of rule-sets, each rule-set associated with a rating category.

15. The method of claim 10, further comprising the step of associating one of a plurality of age-based categories with the document, each age-based category being defined as a range of the document rating.

16. The method of claim 10, wherein the address comprises:

a uniform resource locator address; and

an Internet protocol address.

17. A computer program stored in memory and executed on a computer, the computer program operable to perform the following steps:

receiving a document address of a document available from a computer network;

retrieving a plurality of rating rules, each rating rule having an associated rated word and a numeric value indicating the degree to which the rated word is inappropriate, objectionable, or offensive;

applying the rating rules to the retrieved document in order to generate a plurality of rule ratings;

summing the rule ratings to generate a document rating;

comparing the document rating to a user rating; and

retrieving the document from the computer network if the comparison indicates that access to the document is appropriate.

18. The computer program of claim 17, wherein the document rating corresponds to a plurality of age-based categories, each age-based category being defined as a numerical range of the document rating.

19. The computer program of claim 17, wherein the document rating comprises an override document rating specified by a user of the computer.

20. The computer program of claim 17, wherein the step of receiving a document address comprises:

establishing a connection with a remote site in the computer network to access the document; and

retrieving an Internet protocol address for the remote site.

21. The computer program of claim 17, wherein the document address comprises:

a uniform resource locator address; and

an Internet protocol address.

22. The computer program of claim 17, wherein the user rating corresponds to a current user of the computer program.

23. The computer program of claim 17, further comprising the steps of:

receiving a document rating and a document address from a remote site; and

storing the document rating and the document address in a database.

24. The computer program of claim 23, wherein the steps of receiving and storing are performed in response to accessing the remote site using the computer network.
